- Proven ability to work with high-load, scalable, and business-critical systems.
- Strong debugging, problem-solving, and performance optimisation skills.
- Ability to make technical decisions independently and take responsibility for their impact.
- Strong code quality mindset, with a clear understanding of maintainability, reliability, and long-term system health.
- Readiness to grow into a technical leadership role while remaining hands-on.
- Degree in Computer Science, Software Engineering, or a related technical field.
